I don't know what you're talking about (nor do you, for that matter). Kendo has tons of sparring and it gets VERY intense. Bamboo is a type of wood, and they use that for sparring. Kenjutsu is the old-school martial art of Japanese swordsmanship. It is Kendo's predecessor. The practice lingers mostly on kata, but ought to have some sparring as well. Anyways, you can't ask for Japanese sword fighting and refuse both Kendo and Kenjutsu. That's like asking for a sport that involves striking only with your fists -- but not boxing! Kendo and Kenjutsu is pretty much all you have for Japanese sword arts. If you're interested in something less realistic but very intense and high-action, with weapons that are light enough to allow you to mimic your favorite anime moves, you could check out Chambara. It's pretty much freestyle swordfighting with a Kendo-based scoring system (except they allow leg-strikes) using foam swords. EDIT: oh! How the heck did I forget Iaido?!?!?! Good catch k_snake! However, there's no sparring in Iaido. I've practiced all of the above briefly, and I found Kendo to be most intense, followed by Chanbara, followed by Kenjutsu, followed by Iaido -- based on how much sparring and live drilling there was.
